I WILLIAM BOYLE, OF PHILADELPHIA, PENNSYLVANIA.

WINDOW STAY.

I Application filed October 8, 1920. Serial No. 415,486.

- To all whom it may concern:

Be itknown that" I, WILLIAM BOYLE, a citizen of the- United States, residing at Philadelphia in the county of Philadelphia and State of Pennsylvania, have invented new and useful Improvements in Window Stays, of which the following is a specification. A

My invention relates to new and useful improvementsin a sash stay, and has for its object to provide an exceedingly simple and eifective device of this character adapted to be fastened to a window sash and-frictionally engage one of the walls of the'window casing so as to hold a sash in .any adjusted positionwithin the casing.

A further object of the invention is to produce a Window. stay from sheet metal having a suflicient resiliency to provide a spring pressure between a window sash and a window casing for holding the sash in different adjusted positions, said stay consisting of a body portion having oppositely prowith fingers projecting from the outer ends of said arms adapted to register with chamhers in the. window sash.

With these ends in view, this invention consists in the details of construction and combination of elements hereinafter set forth and then specifically designated by the claims.

In order that those skilled in the art to I which this invention appertains, may under-- stand how to make and use: the same, I will describe its construction in detail, referring by numerals to the accompanying drawings forming a part of this application, in which:-.

Fig. 1, is a perspective view of my improved sash stay.

Fig. 2, is a fragmentary front elevation of a window sash and its casing, a portion thereof being broken away and shown insection'to clearly illustrate the application of one of the sash stays.

In carrying out my invention as here embodied, 2 represents a window casing having a channel 3 therein in' which is. slidably mounted the window sash 4.-

In the side edgeofithe sash is formed a groove 5 lengthwise of the sash and from the ends of this groove project inwardly the chambers or cavities 6 communicating with said groove. In this groove is mounted my improved sash stay 7 the central portion or body 8 thereof lyin entirely within the groove and held in p ace by suitable fasten- 1ng devices 9 such as screws which pass through holes 10 formed in the body. From each end of this body extend the oppositely projecting arms 11 which are arranged at opposite angles so that when in use these arms project outwardly with relation to the s ash as plainly shown in Fig. 2 and with these arms are formed the lnwardly proectlng fingers 12 which register with the chambers or cavities 6 in the window sash, While at the oints of connection between the arms and ngers, which in practice will be slightly rounded and bear against one of the walls of the window casing forming the dow in any adjusted position.

The sash stay is formed from a. piece of sheet metal having suflicient resiliency to normally hold the arms 11 butward or out of line with the body, but when the sash is being .fitted'to the windowcasing some device such as a screw driver or chisel may be placed'between the window casing and sash in the region of the sash stay'so as to engage the arms 11 and when the sash is forced into the casing the arms will be caused to enter the groove 5 suflicientlyto permit said arms to pass into the casing after which the in strument may be withdrawn.

Although I have shown only one sash stay it'is to be noted that one of them is used upon each side of the ,window sash so as to engage both the channels of the window casing inwhich the sash is mounted and where an extra heavy sash is tobe fitted with my device two or more might be placed upon each side thereofas will be readily understood.

Of course-ll do not wish to be limited to the exact details of construction as herein shown as these may be varied wlthin the lim-.

with, a sash stay comprising a body, arms arms projecting from each end thereof in projecting therefrom and fingers carried by opposite directions at angles to said, body, the outer ends of said arms, said stay being and inwardly projecting fingers formed in 10 mounted in the groove with the fingers regtegral with the ends of said arms. 5 istering with the chambers In testimony whereof, I have hereunto.

2. A sash stay formed from a single piece aflixed my signature. v of resilient metal and consisting of a body, WILLIAM BOYLE.
